Product Description:

The MSK100B-0300-NN-M3-AG0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is used in multi-axis machining centers, packaging cells, and material-handling gantries to convert the controlled electrical output of a drive into proportional mechanical rotation. When paired with a compatible controller, the motor supports precise motion control and absolute position tracking through its integrated encoder. In coordinated automation systems, that feedback allows the drive to correct position and speed deviations during acceleration, deceleration, and load changes.

Thermal management relies on passive airflow because the stator is cooled by natural convection, eliminating the need for external fans or liquid circuits. The frame is classified as motor size 100, placing it in the 100 frame class while keeping installation space reasonable. Position data leave the unit through a Hiperface interface, a bidirectional serial channel that sends feedback to the drive and receives electronic nameplate data. Inside the encoder, the primary track is subdivided into 16 signal periods, giving the controller fine angular resolution. The sensing elements use a capacitive principle, which helps the encoder resist interference from magnetic debris. This arrangement keeps the motor housing simple and reduces external cooling hardware.

The encoder stores up to 4,096 shaft revolutions, and its reference output is multiturn absolute, so machine homing can often be skipped after power cycles. The motor is supplied without a holding brake, so any static holding torque must be provided by the drive or by external machine hardware. Torque is transferred through a plain shaft, allowing couplings or pulleys to mount directly without keys. The stator winding uses code 0300, which matches the motor's electrical characteristics to standard MSK drives. The motor also uses the standard housing design with the B-length stack for moderate continuous torque, and the power connector is located on the A side to keep cabling on one face of the machine frame.
